Video Processor for homebrew project ?

Post by lezanderson » 24 Aug 2018 10:45

1 Mbit Versatile SPI / 8-Bit Parallel Bus SRAM with Video Display Controller

I spotted an interesting chip that may be useful for those building those little projects both MTX and Non-MTX related.

The Chip has 128Kbit SRAM and A PAL/NTSC Video chip on it.

There are also quite some good legacy Video processors worth looking at if you're building a homebrew computer system

V6366 these are normally in PLCC68 (internally just an enhanced 6845)
R6545 DIP40 slightly improved 6845
V99x8 VDP..
TMS9918/29
D72020/upd7220 and D72120 are advanced Graphical video controllers
6847... as used in Acorn Atom and Dragon 32...somewhat data even back in the early eighties[/size]
